AMARIA PIERCE, OF PHILADELPHIA, PENNSYLVANIA.

Gas APPARATUS.

Specification of Letters Patent'No. 6,145, dated February 27, 1849.

To all whom, it may concern:

Be it known that I, AMARIA PIERCE, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Gas-Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is an isometrical projection of the complete apparatus, and Fig. 2 is a vertical section of the same.

The base or lower part of the apparatus consists of a square box a, which, with its interior parts hereafter described, constitutes the condenser. On it, and (by means of a flange reaching down to the bottom) into it, fits the ashpit I), also of a square shape, which, half of its height, projects in front, forming a draft-hole, and having a hearth or rim 0 attached to it. On the ashpit sets the main cylinder (Z, which is lined with fire-brick e, and which forms the outside of the fire chamber. This cylinder has a close-fitting top-plate f, with a hole on which the smoke pipe 9 is placed, and on the top of the smoke pipe is set the rosin-kettle h, which has in front a cock 2'. Through the center of the top-plate is a larger hole, in which the retort fits. This retort is of a cylindrical shape, gradually contracting at its lower extremity, and terminating in a smaller cylinder or pipe 70, which passes through the fire grate hereafter described and extends down to the bottom of the ashpit, so as to form a direct connection with the condenser. The retort is furnished on its outside with projecting ribs or flanges Z,

the spaces between which are filled up with I common clay of any kind, forthe purpose of extending in front of said ashpit, whereby it,

is caused to revolve around the pipe 70 to shake the ashes through. The cylinder or pipe 70 fits nicely over a pipe which passes through the bottom of the ashpit, extending upward into it beyond the water or fluidline, and downward into the condenser somewhat below the water-line.

F astened or cast to the underside of the bottom of the ashpit, and extending clownward into, and nearly to the bottom of, the condenser is a spiral flange r, commencing near the pipe 9, and winding around at uniform distances until it terminates, by a right-angular turn, against the back-plate of the condenser. Here, at its terminus, inside of the flue formed by the said spiral flange, a pipe 8 passes through the bottom of the condenser, and by an elbow-joint leads the gas to the gasometer;

The retort is covered by a lid 6, which has a small central pipe 10 tending upward and passing into the cup 2), which is cast with the lid, and the upper edge of which cup is somewhat above the upper edge of the lastnamed pipe. This said small central pipe at has a loose cover, the lower part of which consists of a pipe w, fitting over it and into the cup 12, in such a manner as to leave a sufficient space between the said pipes u and w, and between the pipe to and the cup 4), for the rosin to pass into the retort. On the top (and cast to) the loosecover is a funnel 00, which receives the rosin from the cock of the rosinkettle, and passes it through the perforations y in said funnel, said perforations being placed between the outside of the pipe to of the loose cover, and the inside of the cup '2) on the lid of the retort. z is a lid covering the opening in the topplate f, through which the fuel is introduced into the fire-chamber.

The ashpit is filled with water, or any other suitable fluid, to a proper height, for the purpose of forming a fluid-joint between the retort and the condenser, so that the retort and the condenser, so that the retort may be taken out and put in without the necessity of having a permanent joint. The condenser is filled with water, to about half its height, for well known purposes.

What I claim as my invention, and desire Which being constructed, arranged, and opto secure by Letters Patent, is: erating substantially, in the manner and for 1 l. The ribs or flanges Z around the retort. the purposes herein above described. 2. The passin of the lower end of the w 5 retort through tlie fire-grate m so as to con- AMARIA PILRCE' nect it directly with the condenser. Witnesses:

3. The immersing of the lower end of the FRANCIS BENNE,

retort in Water or other suitable fluid all of J. MITCHELL.
